Question

当我使用JSF 2.1提交表单并使用JBoss服务器时，会出现标题上的异常。

我试图使用和学习hibernate注释。

我的实体bean是这样的：

@NotEmpty
@Temporal(TemporalType.DATE)
private Date date;

我收到此错误页面：

JBWEB000071: root cause

有人知道为什么吗？

谢谢，

即使我不理解@NotEmpty和@NotBlank之间的相似之处，这篇文章也适用于我：

Error with validator (No validator could be found for type: java.util.Date.)

此致

修改

即使我在javax.servlet.ServletException: HV000030: No validator could be found for type: java.lang.Integer得到了重复问题的评论，我只想清楚地知道这不仅发生在整数，而且还发生在日期也许对于我们 - 不知道有多少其他类型。

我同意在使用它们之前尝试理解注释的声明，但我也说我们没有足够的文档。

javax.servlet.ServletException：HV000030：找不到类型的验证程序：java.util.Date
